Recently I tried one of the collagen serum which I bought from Hatyai. It can be found in any 7-11 store in Thailand and it cost 39 baht. The packaging was simple and special too. Easy to carry around and easily open and close with the cap.
Royal Beauty Collagen Serum+Vit C has a mild orange scent. Vitamin C concentration help bounce clear skin tight. The serum is very light, and can be easily absorbed into the skin and effectively. The serum is clear gel with tiny orange beads.
Wash your face first. Then gently apply it to your face.
Mainly this serum works for whitening skin tone and reduce dark spots. Strongly recommend to use daily on morning and evening. You will notice the result within 3~5 days.
